Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contiguous bubble element, and more specifically to a merge element having a large gap tolerance.

[Prior Art] Is the merge gate in a discrete disk bubble device two bubble data flows? single co-d
It can be used to attach to the flow of water. For example, a mar/gate can be placed on a track leading to one detection device so that the same detection device can sense any bubble event in the loop.

Merge gates for ion-implanted contiguous disk bubble devices are available from BellSystem
Technical, Journal, Vol. 59, No. 229 to No. 257 (February 1980), as described by Ne 1301 et al., and also in the specification of U.S. Pat. When subjected to a counterclockwise rotating in-plane magnetic field, these bubbles move along the input track 2, which performs a very good transfer, and the human-powered track 4, which performs a poor transfer 7, to the merge region 6. The merge gate relies on a tip-to-tip relationship between the two input paths. In order to have a large tolerance to the gap, ie a bias field range of 10% or more, the spacing of the gap must be close to the face of the bubble.

A unidirectional transfer track for a continuous disk bubble element is described, which is transferred to the tip pornon on the side of 100,000 to 20,000.

SUMMARY OF THE INVENTION The object of the invention is an improved merge element for contiguous superdisc bubble elements? It is to provide.

Another object of the present invention is to provide a merging element that has a large volume to gap gap.

The above and another object of the present invention is to provide a merging element with a large tolerance to the gap, wherein the tip portion of the first quadrangle substantially faces the pointed concave portion of the second quadrangle to form a merging region. achieved. Its output drag is
It is provided in relation to the merge area described in Section 2. In 1 Yoshiji @Siri, the merge element is passive and has no conductor. In another example, a nine-channel dynamic merging element is reading a conductor. In this merging element with a large gap tolerance, the gap can be larger than twice the diameter of the bubble and still provide a 10% bias field range.

They are transferred smoothly in the direction of the truck, but the transfer is custom-made by a human-powered truck 18

The manual drag 18 on the non-ion implanted region 12 has a tip portion 26 that leads to output drug portions 24 and 20. The tip portion 26 has 28 protrusions. The manual puller (4) 22 on the non-ion implanted region 14 is guided into the pointed recessed portion 30. The concave portion 30 has a bottom portion 32 . The tip portion 26 is separated from the tip portion 60 by a gap 64, which is the ion implantation region. Is the concave portion a concave surface adjacent to the ion implantation region that has a convex surface? Defined as a non-ion implanted region with Is the tip concave? A convex surface that is adjacent to the ion implantation region? Defined as a non-ion implanted region with

The merging operation of the two bubble data streams in the merging element 10 occurs between the protrusion 28 of the tip portion 26 and the bottom portion 32 of the concave portion 60. The operation of this merge element is
A tolerance of 1'1Effi is provided for the distance or gap between the protrusion 28 of the tip portion 26 and the bottom portion 32 of the pointed recess portion 60. Is the gap at least 23 times wider than the bubble diameter? It can also have a 10% bias field range. A bias field range of 10% or above μ is desirable for operation of RE elements in magnetic bubble elements. Do smaller gap dimensions result in a larger bias field range? arise. If you line up, bubble (7) II
Does a gap 17 times the diameter have a bias magnetic field range of 12 yen? give. In contrast, the bias field range provided by the prior art merge gate shown in FIG. 1 is 5% at a gap of 17 times the bubble diameter. The gap in this prior art merge gate must be approximately the same size as the actual bubble diameter to obtain sufficient bias field coverage. Therefore, the merge element 10 of the second AIJ can be operated with a wider gap than the prior art merge gate of FIG.
It also has greater tolerance to variations in gap size. Punching this gap becomes extremely important as bubble and element dimensions are reduced to increase the void density of contiguous disk bubble elements.

Merge element 10 operates as follows. human powered truck 18
The upper bubble is subjected to a clockwise rotating in-plane magnetic field and is transferred along input drag 18 from left to right, via protrusion 28 to output drag section 24 and then to output drag section 20. 7] I can do it.

As the in-plane magnetic field is rotated clockwise, the bubble is transferred to the bottom 62 of the pointed recess f+30 a (FIG. 2B) and protrudes across the gap 34, as shown in FIGS. 2B-IZD. 28 (FIG. 2C) and then down the side of the tip section 26 to the output drag section 24 (FIG. 2D).
